Answer:
14m+60
Step-by-step explanation:
=3m+4(m+12)+(7m+12)
removing bracket, we get
=3m+4m+12×4+7m+12
=3m+4m+7m+48+12
14m+60

Because the two triangles are similar, one is a scaled down version of the other.
You can figure out that scale by comparing two matching sides, in this case AD and AB.
AD = 2 and AB = 2+4 = 6
So 2/6 = 1/3, telling us each side of the smaller triangle is 1/3 the size of the original.
Now we need to find ED and know CB = 12. Knowing ED = 1/3 of CB:
ED = 1/3 • 12 = 4

Answer:
4
Step-by-step explanation:
f⁻¹(x) = x²+3, but none of that matters, since f(f⁻¹(x)) = x
